【 摘 要 】

This article proposes a theoretical investigation of the contact of composite reinforcement with concrete under the action of an axial tensile load. The purpose of this article is to identify existing methods of specifying stress-strain state of concrete and reinforcement contact zone under the influence of an axial tensile load and proposals of analyses of stress-stain condition of anchoring flexible connections with concrete zones based on the conducted experimental studies. The article analysed methods for calculating the adhesion of reinforcement to concrete by Russian and foreign scholars, and proposes an example of engineering calculations of flexible connections for three-layer wall panels. It was revealed that this method considers limited condition; however, taking into account the actual stage of work on composite flexible connections under calculating and constructing three-layer wall panels makes the most informed project decisions about location and number of flexible connections in the structure, considering the the safe exploitation is provided. Based on the results of experimental studies, the article proposes to distinguish three main Stress-Stain State (SSS) of composite glass flexibles bolting resistance in the considered lightweight concrete. The research is carried out within the project funded by Fund for Assistance to Small Innovative Enterprises in Science and Technology Grant, programme UMNIK, contract 11905GU/2017 from 03.07.2017.
